UNITED STATES PATENT (Demon.

EPHRAIM H.. ADAMS, OF LYKENS TOWNSHIP, CRAWFORD COUNTY, OHIO.

IMPROVEMENT IN LAND-ROLLERS.

Specification forming part of Letters Patent No. 1 67,380, datedSeptember 7, 1875; application filed April 8, 1875.

To all whom it may concern:

Be it known that I, EPHRAIM H. ADAMS, of Lykens township, in the countyof Crawford and State of Ohio, have invented a new and usefulImprovement in Land-Rollers; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings making a part of this specification, in which-Figure l is a plan view of all its parts. Fig. 2 is bracket I, attachedto F and G. Fig. 3 is a section of the plate P as attached-to roller 0and side J. Fig. 4 is a plan of the draw-bar T.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation.

The object and purpose of my improved roller are to allow the separaterollers the means of a limited adjustment on the central draftrods T T,so as to each separately follow the inclination of the ground over whichit passes, the front roller acting independently of the rear ones, androlling as required by the loose coupling of the clevis, by which therear rollers are attached thereto.

I construct my rollers as follows-that is to say, of wood, by putting onstaves or strips to the circular ends 0 in any suitable manner. On thesaid circular ends 0 I securely fasten a plate, P, of which. Fig. 3 is asection. The pin K is driven tightinto ahole prepared for it therein,and the flanges being bolted thereto, the journal M is embraced by thetwo halves of the cast-iron journal box N, the upper half of which issecured to the ends of the sides J J, which form part of the severalframes F G H, and the lower half is bolted thereto. front of the tworear rollers, is also of wood,

The cross-bar D, which stands in and the coupling-piece E is gained intothe under side thereof. At the inner ends of the frames F G, whichembrace the rear rollers, I put a bracket, I, with a lip bent at eachend, for the purpose of preventing the roller raising or lowering beyondthe limit assigned to it. I insert my tongue in the under edge of thefront frame H, secured there by bolts passing through the same. Throughthe frames F and G I place a draft-rod, T T, on which the said framesmay have a rotary motion, for the purpose of accommodating themselves toany ground and over any obstructions. Through the front frame H I put aneyebolt, L, through which the clevis Q passes, and the bolt R passesthrough the couplingpiece E and secures the clevis thereto. The draw baror rod T is made with a wide flange to bolt it to the cross-bar D. Theremaining part of the rod is round, so as to allow free play of theframes F and G thereon within the limit allowed by the bracket I.

I do not claim any novelty in the construction of the rollers, neitherin the manner of their adjustment in the frames, or in the manner ofattaching the rear to the front frame, or in the manner of attaching thetongue to the front frame.

Having thus described the construction and operation of my invention,whatI do claim as new, and desire to secure by Letters Patent, 1s

The stop-plates I I, in combination with the pivoted roller-frames F Gand transverse bar D, as and for the purpose set forth.

In witness whereof I hereunto set my hand this 26th day of March, A. D.1875.
